Watch: Pixar's Charming 'Monsters University' Mother's Day Video

"They'll always be your biggest fan." It's Mother's Day this weekend in the US, and of course Disney/Pixar is celebrating it with a fun promo video for their animated summer movie - Monsters University. The video features a few clips of the amusing monster mother character, Ms. Squibbles, who is Squishy's mom from the fraternity that Mike and Sully join. We've seen Disney make plenty of these kind of promos for all sorts of different holidays, but this is a fitting one from Pixar since Ms. Squibbles is an important part of the cast and story in Monsters University. Check it out below. To all the mom's out there - Happy Mother's Day!

A look at the relationship between monsters Mike (voiced by Billy Crystal) and Sulley (voiced by John Goodman) during their days at the University of Fear -- when they weren't necessarily the best of friends.

Pixar's Monsters University is being directed by Dan Scanlon, who went from animator to storyboard artist to writer to co-director on Mater and the Ghostlight, making his feature directorial debut. This is a prequel to Pixar's animated movie Monsters Inc, originally released in November 2001. Disney/Pixar has Monsters University set to arrive in Disney Digital 3D everywhere starting June 21st this summer. In theaters soon.

I haven't any problem with making sequel in pixar corporation (waiting f-ing soooo long for incredible 2) but i know i love pixar and life is short too, i think i accept a sequel from them just when they deliver one original art beside that sequel in same year. Without that i always think i miss something in that year
